CLEMENT C. OLAVVSON, OF NEWVARK, NEW JERSEY.

COIN-CONTROLLED AIR-PUMP-OPERATING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 619,279, dated February14, 1899. Application filedJune 30, 1898. Serial No. 684,779. (Nomodel.)

To all whom it may concern.-

Be it known that I, CLEMENT O. CLAWsoN, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Coin-Controlled Air-Pump-Operating Mechanism; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersof reference marked thereon, which form a part of this specification.

The present invention has reference to a novel construction ofcoin-controlled mechanism in which by the depositing of a coin apump-operating mechanism becomes freed and can be worked by the turningof a crank.

The object of my invention, therefore, is to provide a novelconstruction of apparatus of this character in which after the mechanismhas been freed by a deposited coin one or more air-forcing pumps can beoperated to drive or force the air through a pipe or tube connected withthe casing of the apparatus and from which the air can be forced toinflate the object connected with or attached to the end of the saidtube.

One of the principal objects of my present invention is to provide amachine or apparatus which can besecured to the side of a building orpost to enable riders of bicycles to inflate the tires of their vehiclesalong the road by simply dropping a coin into the slot of the apparatus,attaching the air-inflating tube connected with the apparatus to thetire of the wheel of the bicycle, and by turning the crank of theapparatus forcing air into the tire to fully inflate the same.

A further object of my invention is to provide an apparatus or machineof the nature and for the purposes stated which shall be of a compact,reliable, and efficient construction.

The invention therefore consists in the novel construction ofcoin-controlled mechanism and means for driving or operating an air pumpor pumps; and the invention, furthermore, consists in the novel featuresof construction and the several arrangements and combinations of theparts of such mechanism, all of which will be fully described in theaccompanying specification and. finally embodied in the clauses of theclaim thereto appended.

The invention is clearly illustrated in the accompanying drawings, inwhich- Figure 1 is a front view of my novel construction of apparatus,and Fig. 2 is a top view of the same. Fig. 3 is a front View of theapparatus with a pair of doors in the front of the casing removed toillustrate one arrangement of the controlled mechanism within thecasing, the several parts being represented in their normallyinoperative positions; and Fig. 4 is a horizontal section of the casing,taken on line 4. 4 in said Fig. 3, said view illustrating in top viewthe general arrangement of the operating mechanism embodyin g theprinciples of this invention. Fig. 5 is a longitudinal vertical sectionof the easin g with the pump-operatin g mechanism represented in frontelevation,the coin-controlled mechanism being represented in its freedposition to permit the actuation of the pumpoperating mechanism. Fig. 6is a horizontal section of the several parts, said section being takenon line 6 6 in said Fig. 3. Fig. 7 is a longitudinal vertical section ofthe casing and a front elevation of one arrangement of three air-pumps,a three-way valve and connecting-tubing, and a means for operating saidpumps; and Fig. 8 is ahorizontal section taken on line 8 8 in said Fig.3. Fig. 9 is a vertical cross-section taken on line 9 9 in Fig. 5,illustrating a portion of the coin-chute in crosssection and theoperating mechanism directly connected therewith being presented in endelevation, but the arrangement of air-pumps being omitted in this view.Figs. 10 and 11 are a face and edge view, respectively, of a cam and aportion of the operating-shaft on which it is arranged for working theair pump or pumps. Fig. 12 is a longitudinal vertical section of one ofthe air-pumps. Fig. 13 is a horizontal section of the same, taken online 13 13 in said Fig. 12; and Fig.14 is a similar section taken online 14 14in said Fig. 12 when looking in the direction of the arrow ain said figure. Fig. 15 is a side view of a guide-frame and rollersemployed in connection with the air-pump. Fig. 16 is a longitudinalvertical section of said guide-frame, and Fig. 17 is a plan view or topview of said frame. Figs. 18 and 19 are detail views of a pair ofreceivers or holders adapted to'embrace and retain the air-pump inproper positionin the casing of the apparatus, and Figs. 20 and 21 arethe respective end views of the devices illustrated in said Figs. 18 and19.

Similar letters of reference are employedin all of the above-describedviews to indicate corresponding parts.

In the said drawings, A designates a suitable casing of iron or wood,which is preferably of the shape indicated in the several figures of thedrawings, being provided with a back a, sides ct, and top and bottomsides a In the said back a there is a suitable arrangement of holes, asa*, for the reception of screws or nails, whereby the device can besecurely attached to the side of a building or post, as will be clearlyevident.

The sides and the top and bottom pieces of the casing A are preferablyprovided with a suitable and ornamental molding a and a cross piece orbar a connects the two sides a of the casing A in such a manner. that anopening a will be formed at the top and an opening a? will be formed inthe lower portion of the front of the casing, as will be clearly seenfrom an inspection of Fig. 3. Said openings of and a are formed on threeof their marginal edges with flanges a", on which can be made to restthe doors I) and b, as indicated in Figs. 1, 4., 8, and 9. Each door 1)and b has'a flange or lip b which fits under the edge a of each openinga and a and in the door I) is the usual form of coin-slot b and a lockI), while the door I) is provided with a lock b whereby, as will beclearly evident, 'the said doors can be securely held in their lockedpositions in the said openings a and a of the casing A to protect themechanism within the said casing.

In suitable bearing-portions in the cross piece or bar a and in the backa of the easing A is rotatively arranged a main shaft 0, which projectsfrom the front of the said piece or bar a. and has a crank a securedthereon,

as clearly indicated in Figs. 1, 2, and 4. On the said shaft 0 I havesecured a peculiarlyconstructed wheel d, which is provided with a hub dand a set-screw d for firmly securing it upon the shaft 0. Said wheel (1has a web portion (1 from the inner side of which extends an annular orcircular flange 01 which, however, is eccentrically placed in relationto the central longitudinal axis of the wheel 'd. The said web (1 has anopening d in the one side thereof, which isfor the purpose of reducingthe weight of metal and to facilitate the getting at the set-screw d insecuring the said wheel 01 in its operative position upon the shaft 0;but said opening d is not essential and may be dispensed with, ifdesired. The periphery of the said wheel d is provided with a suitablearrangement of ratchetteeth d formedin the manner clearly illustrated inFigs. 3 and 5, and f is a suitable dog or pawl pivotally arranged on apin wheel.

f, extending from the back of the said cross piece or bar a, and f is aweighted arm on said dog or pawl to cause the part f of said pawl tohang in constant sliding engagement with the peripheral surface of thesaid wheel d and against the ratchet-teeth thereon to permit of theforward rotary movement of said wheel, but to prevent any backward.movementof said wheel by the said part f coming in stopping engagementwith the angular portion of the ratchet-teeth of the said At a suitablepointin the upper righthand portion of the periphery of said wheel atwhen the parts of the mechanism are in their normally inoperativepositions there is a squared projection d7, which forms a suitable stop,for the purpose to be hereinafter more fully set forth. Directly back ofsaid projection d the said wheel is provided with a pair of inclinedsurfaces d and d", the same forming a -shaped portion between the saidprojection d' and the following ratchettooth d, as will be clearly seenfrom an inspection of said Figs. 3 and 5. Directly back of the saidwheel (1 and secured upon the said shaft 0 by means of a set-screw gbetween the hub d of the wheel at and the inner surface of the back aofthe casing A is the hub g of asuitable cam-disk g, the purpose of whichwill be more fully set forth in connection with the description of theair pump or pumps. As will be seen more especially from an inspection ofFig. 8, the said back a of the casing is provided with a suitable posta, having a screw-threaded opening a Rotatively secured on a pin orscrew j, screwed into the said opening in the end of thepost a is a diske, having a circular peripheral edge portion a and aneccentrically-placed curved edge portion e a pair of diagonallyarrangedportions (2 and a being provided to connect the said portions 6' and ein the mannerillustrated more particularly in Figs. 3 and 5. Secured tothe said disk 6 by means of screws 6 or in any other well-known manneris a second disk 6 which is provided on its peripheral su rface withsuitable ratche tteeth 6 On a suitable post or pin h is a hub h, whichis provided with a downwardly-extending arm h having a finger portion77, at its. lower end projecting at a right angle therefrom and beingnormally in sliding en gagement with the edge portions 6' or e of thedisk 6. Said arm 71, has projecting from one edge thereof an arm ithaving a finger portion h, formed at a right angle at the lower endthereof and extending directly beneath the discharge-opening of asuitable coin-chute 'i, as clearly indicated in Figs. 3, 5, 6, and 9. Toprevent any backward movement of the two disks e and e, I have pivotedto said arm 71, a suitably-constructed dog orpawl h",whicl1 slides overthe ratchet-teeth of said disk (2 When moving in the proper direction;but which prevents any backward movement thereof, as will be understood.Pivotally arranged upon the pinj,hereinabove mentioned,

is a rod or lever 7c, which is provided at its free end with a screw loand a roller or wheel arranged on said screw. Said rod or lever 70 isprovided with a pin. or post k and the arm h hereinabove mentioned, hasan eye or loop 71 the said loop or. eye and the post 70 being connectedby a coiled spring m, substantially as illustrated in Fig. 3. The normaltendency of this spring m when the several parts of the mechanism are inthe positions indicated in said Fig. 3 is to force the end of theupwardly-extending arm 71, directly against the stop portion of theprojection d of the wheel d, with the finger portion h of the arm h inholding or locked engagement with the stop formed by the diagonalportion 6 connecting the peripheral edge portions e and e of the disk 6.At the same time the tinger portion 7L6 of the arm h5 is forced updirectly against the under surface of the discharge-openin g in thecoin-chute 'i, and a coin which has been dropped in the chute i will beretained therein, near the bottom, by resting on the said finger portionh? and against the inner curved surface 1" of the coin-passage withinthe chute, as indicated in said Fig. 3. Said spring m, connected withthe arm or 1ever It, will also cause the constant operative rollingcontact of the wheel or roller k with the eccentrically-arrauged annularflange d of the wheel (I. As will be seen from Figs. 3 and 5, pivotallyattached tothe said rod or lever k is a suitable dog or pawl is, havinga tooth k which is forced in operative engagement with theratchet-teeth-e of the disk e by the weighted end portion 70 of saidpawl. From the above description of these several parts and aninspection of said Fig. 3 it will be clearly evident that the mechanismis locked and that the shaft 0 and parts connected therewith cannotpossibly be operated until the mechanism is released in the manner to bedescribed. The said coin-chute 2' consists, essentially, of a pair ofpeculiarlybent plates 01 and 71 said plate 7? having suitably-spacedribs t upon which the said plate 11 is secured by means of screws 2' toform the complete chute. Said plate 2' also has a pair of brackets iwhereby the chute can be secured in position within the casing A againstone of its sides a, as indicated in the several figures of the drawings,with the inlet or mouth of the coin-chute directly back of the coin-slotin the door I) and the outlet of the said coin-chute 71 directly abovethe finger portion of the arm 7L As will be noticed from Figs. 3, 5, 6,and 9, the said plate i is also provided with a perforated bearingportion 6 which extends directly over the edge of the plate 4? and abovea slot i in said plate. (See more particularly Fig. 9.) In this bearingportion 2' and in a suitable perforation in the top (L of the casing A,I have arranged a rod '21, provided on the outside of said casing withan ornamental knob 71. The

lower portion n of said rod, as will be seen from said Fig. 9, extendsbelow said bearing 2' and down into the said slot i in the plate '6 ofthe coin-chute, a portion of said rod extending into the coin-passage ofthe chute z. Said rod is normally held above the coin which has beendeposited in the chute by a spring 02 which encircles the said rod n onthat portion located between the inner surface of the top of the casingA and said bearing 1' in the manner illustrated in Figs. 3 and 5. Now assoon as a coin has been dropped into the said coin-chute t' it will beretained in the position indicated in dotted outline in said Fig. 3. Byapplying a downward pressure upon the knob n of the rod 71. the end a ofsaid rod is brought down upon the edge of the coin. The latter will thusbe caused to partially project from the discharge-opening in the chute1', thereby exerting a pressure upon the finger portion h of the arm7L5, whereby the arm 71 will be disengaged from the projection d on thewheel cl and the finger portion 71 of the arm h will be lifted away fromthe portion 6 of the disk 8, as clearly illustrated in Fig. 5, with thecoin still retained in the position indicated in said figure. The crankconnected with the shaft 0 can now be operated to turn said shaft andall the parts connected therewith. In the meantime the spring m causesthe roller or wheel 70 on the arm 7a to roll against the annular surfaceof the eccentric projection or flange d of the wheel 61, which with eachrevolution of the shaft 0 and the wheel (1 causes a vibratory motion ofthe rod or lever 70, and hence the latter by means of the dog or pawl kproduces an intermittent rotary motion of the disk 6 and disk 6 on thepin j. As soon as the highest point of the eccentrically-placed curvededge portion 6 engages the finger portion h of the arm [L3 said arm 713and the arms 722 and 71 will be moved slightly forward, owing to apartial rotation of the hub h upon its pivotal post or pin h, wherebythe finger portion h of the arm ha is brought farther away from thedischargeopening in the chute and the coin is permitted to finally dropdown into the lower part of the casing A. As soon as the coin has passedfrom the chute v; the spring at causes the finger h4 of the arm 7L3 torest in sliding contact on the circular edge e of the disk 6. The shaft0 and parts thereon are thus still permitted to be operated, the saidcircular flange d on the wheel cl being so arranged that one revolutionof the flange and wheel will cause but a partial rotary motion of thedisks 6 and 6 equal to the distance between two consecutiveratchet-teeth on said disk a These several parts of the mechanism are soarranged and timed that about fifteen complete revolutions of the shaftand wheel 61 will have caused but one complete e Z and a connecting-wallZ holding or locked engagement with the projection d on the wheeld,-with the several parts of mechanism in their normally inoperativepositions and the finger portion h of the arm 71, directly beneath thedischargeopening of the coin-chute t', as indicated in said Fig. 3.second operation when another coin is deposited into the chute i.

I will now describe the manner of arranging and operating the air pumpor pumps when the shaft revolves in the manner just described.

In Figs. '7 and 8 I have illustrated one manner of arranging andsecuring the air-pumps in their operative positions to be worked by thecam-shaped disk g, which is connected with the shaft 0, as above stated.Secured to the back a of the casing A, preferably upon suitably disposedenlargements or projections, as (1 (see Fig. 8,) is a receiver or holdersection Z, to which is secured a second receiver or holder section thesame being secured together in such a manner to form a socket orreceiving portion in which a pump 0 is securely and operatively held.Said section Z is formed with a semicylindrical part The outer portionof said part Z is made with angular sides Z and has holes Z whereby itcan be secured by means of screws upon the projection a Saidsemicylindrical part Z also has oppositely-extending lugs or ears Z and1 which are provided with holes or perforations Z and directly beneaththe lug or ear Z there is a curved or cut-away part 1". Connected withthe said lug or ear 1 is an upwardly-extending arm Z which has alongitudinal rib Z on its inner surface, said rib terminating at a pointZ on said arm, substantially'as illustrated in Fig. 18. At one side ofsaid arm Z there may be a laterally-extending leg Z having a perforatedlug l for securing it by means of a screw Z to the back a of the casingA. The said receiver or holder section Z also has a semicylindrical partZ and a connecting-wall Z and is provided with opp0 sitely-extendinglugs or ears I and Z, which are provided with holes or perforations ZDirectly beneath the lug or car Z is a curved cut-away part Z Connectedwith the said lug or ear Z is an upwardly-extending arm Z which has alongitudinal rib or projection Z terminating at a point Z on said arm,substantially as illustrated in Fig. 19. When the section I has beensecured against the back of the casing A, the section Z is placed uponthe section Z, (with the pump in the socket formed by the two sections,)so that the lugs or ears of the section Z will rest upon the lugs orcars of the section Z and the rib Z on the arm Z will rest directly uponthe rib Z of the arm Z the two sections then being-firmly securedtogether by means of screws Z all of which will be more clearlyunderstood from an inspection of Fig. 8. When secured in this manner,the respective arms Z and Z The device is now ready for a nipple 0therein;

will have a suitablespace between them and will form a guide for aflanged roller 8, connected with a guide-frame u on each pump 0. "Eachair-pump, of which there may be one, two, three, or more, arrangedbetween a corresponding number of pairs of receiving or holdingsections, may be of any well-known construction, the pump herein shown.consisting, essentially, of a main cylinder 0, having aclosed bottom 0,an air-outlet 0 and a The upper portion of each pump has an internalscrew-thread-0 into which is screwed a ring 0 Movably arranged in saidring is a cylindrical tube 0 having an annular flange 0 which normallyrests againstapacking-ring p at the bottom of said ring 0 to prevent thewithdrawal of said tube .0 after these parts have been properlyassembled. Secured to the bottom 0 of said tube 0 which is also providedwith suitable air-passages e is a cap 0 and a cup-shaped washer 0 bothof the usual form of construction, and between said cap 0 and the bottomof the cylinder 0 there is a spring o When all the parts hax e been puttogether in themanner illustrated in Fig. 12 and the tube 0 is moved upand down in said cylinder 0 against the action of the spring therein, aperfectly-operating air-pu mp is produced and the air can be forced fromsaid cylinder 0 through the discharge-opening therein into a tube orpipe 15.

Loosely arranged in the open end of each tube 0 of the pumps is theguide-frame 11., above mentioned. Each frame is provided with a flangedportion a, which rests di rectly upon the upper flanged or beaded edgeof the said tube 0 Said frame 2' is open, as at 11. and rotativelyarranged on a pin u extending across said opening, is a wheel or rolleru, which when the pump or pumps have been securedin the casing A isforced into operative rolling contact with the peripheral surface of thecam-disk g by the action of the spring 0 in the pump.

In order that the reciprocatory action of i the tube 0 may be properlyguided when the machine is in operation and to maintain the properalinement and operative rolling contact of the roller or rollers wagainst the camsurface of the disk g, each guide a has a pair ofoutwardly-extending and perforated ears or lugs 11. between which, on apin 8 I have arranged the flanged rollers s, hereinabove mentioned. Saidroller 8 is in alinement with the roller u, and its flanged portion 8extends between the guide portions of the arms Z and 1, connected withthe respective receiver or holder sections Z and Z", as more clearlyillustrated in Fig. 7. Thus it will be evident from an inspection ofFigs. 3, 5, and 7 that after the coin-controlled mechanism has beenfreed in the manner hereinabove set forth and the shaft 0 and cam-disk gare being revolved the action of said cam-disk against the rollers orwheels 8, connected with the pumps, is such that during each revolutionof the shaft 0 two pumps are constantly forcing compressed air throughthe tubes or pipes t, connected with the respective pumps. As shown inthe several views of the draw ings, the said tubes or pipes tareconnected with a suitably-constructed valve-chest '11,.

provided with a three-way valve of any wellknown construction which hasan outlet pipe or tube 1). Said pipe or tube 1 is connected with anipple o in the bottom or side of the casing A, and connected with saidnipple o on the outside of the casing, is a flexible tube or pipe vwhich is provided with a suitable mouthpiece i= which can be placed overthe tire-valve of a bicycle for inflating the latter or over any othervalve connected with some other article to be inflated with air.

Although in the present construction of apparatus I have illustrated anarrangement of three air-pumps, it Will be clearly evident that I mayuse but one pump, or I may employ two or more pumps without in the leastdeparting from the scope of my present invention; and, furthermore, I donot wish to be understood as limiting my present invention to the exactarrangements and combinations of the several mechanisms herein set forthnor to the details of the construction thereof, for I am fully awarethat they may be departed from without departing from the scope of mypresent invention.
